What’s new about the emergency ops centre
A seismically reinforced and modern emergency operations centre.
Adaptation
How have major emergency services been adapted
180 seismic retrofits / replacements, e.g. small but critical pump stations, or transmission mains, police and fire stations.
Adaptation
Who creates models forecasting disaster impacts
California Utilities Emergency Association
How are models forecasting diaster impacts used in recovery?
Look for interdependences between energy and utility systems to bring them back on line as quickly as possible (e.g. pumping stations need power, first). Energy / telecoms / water / gas are all needed together
Why are the rich at an adavantage overall in EQ situations (HEDCs)
Might have better transport links – aid/held takes less time to arrived – injuries don’t become fatalities
Rich / wealthier / developed – better infrastructure, with aseismic buildings
Lower population density, lower exposure to hazards, less chance of being trapped by landslides or collapsing buildings
